Abstract: This paper presents an analog baseband section that implements the beamforming functionality of a 40 nm digital low-power (LP) CMOS 60 GHz transmitter. An input 1dB compression point larger than 240 mV peak over the whole band is obtained, in a circuit operating with a 1.1 V supply. The targeted phase shift resolution of 22.5 degrees is obtained. Fully automatic, digitally assisted DC offset compensation is also present on-chip. The current consumption is 70 mA
